I didn't change anything on the fps handling 5.5.2. When you choose 23.976 this value is passed to the encoder.
Actually the encoder will encode with 24000/1001 which is the mathematically correct value.
In the media overview Premiere just shows the rounded number 23.98 (in comparison Resolve for example shows the correct 23.976).
You can also see the right number in Premiere: if you go into the "interpret footage dialog" there is an option "Use framerate from file" which shows 23.9760 and tells you that the file has the correct framerate.
If you manually interpret footage with a fixed value of "23.976" this might be wrong and cause a sligtly different playback length as you are experiencing it, because the actual unrounded value should be 24000/1001.
Bottom line: just use the files as they are, don't interpret them. Then everything will be ok. :-)
